, Be it known that I, Cram A. Hor, a citizenof the UnitedStates, resding at Buffalo in the count of Erie and .State of New York, haveinvented new and useful I1nprovements in v Apparatus for T routingCanned'Goods, 0t whichtheiollowing is a specification. v r

-Thisinvention relates to an exhau'ster which is employed in foodcanning factories for heating the cans while beingfilled with the goodsto be canned and drawing oil-or exhaustinganyv airthat may be'present inthe cans, so that when the cans aresubse luentlv, hermeticallysealed thesides and ends of the cans are not liable to bulge out by fermentationwithin the cans orjby the high temperatures to which thesaine may beexposed wheni-sub'sequently stored. T r 1 L It is the objectotthisinvention to produce a machine fort-his purpose which is compactinconstruction .and' capable of.

handling a comparatively largernuznber of cans in agiven time, also toso design the machine that the heatingof the cans is efi'ected-by aminimum expenditure of steam,

also to propel the cans eificiently bvthe ext-- penditure of acomparatively'slnall; amount of power, and, to improve the machine .invarious details as will presently appear lathe accompanying drawings: IFigure-1 is a vertical longitudinal section oi"v an exhauster embodyingm improvements.

Figure 13is a vertical section taken on line '1 :5-l3, Fig.5. Sin'iilarcharactersof reference,indicate corresponding parts throughout the several views.f The main frame of this machine preterably comprises acircu'lar base20, a pedestal 21 secured at its lower end to said base, an uppersupporting head 22 secured to the top of the pedestal and a lowersupporting head 23 securedto the pedestal intermediate of the base andupper: head. i The treating principalfof the mechanism for propelling!the cans while the sanie are being heated is forn'red by adownwardly-tapering bottom 241 which issecured at its lower sinallcnd tothe lower supporting heath/an upright cylindricalwall or body 25 risingfrom the "upper outerv edge of the-bottom, and a hori 1 Zontal removabler1ng-shaped cover 26 provided at itsinner and outer edges withdepending"annular flanges 27, 2-8 which are adapted to;dip into waterarranged inau nular grooves or channelsf 29, 30 on the uppersupportingheadand wall and" form a heated, which. conveyor in thepresentinstancecoinprises a plurality of horizontal conveyer rings 31, 32,83,perferablv,=- though not necessaril v. three in number. These rings! are"of dilicren't diameters and; nested concentrically one withinrtheother,so that i their upper surfaces are fiush 'or nearly so; as shown inFigs. land 6, These several, conveyer rings" are rotatably supported by,a plurality of driving rings 36, 3 7 arranged in avertical row andjourrur-ledon the'peripherv 'of thepedestal- The lower-- niost drivingring IBTyis' connected by radial 'ch'an ber 24 within which is arrangedthe arms 38 with the inner c-onvever ring 33 and held against verticalmovement between the upper supporting head and an upper" stationarycollar '39 secured to the pedestal,

the-lower drivingring 35 is connectedby ra f dial arms lO- with the,outer conveyer ring 31 and is held against vertical displacement betweenthe lower supportinghead and stationary collar 41 on the pedestal, andthe intermediatedriving ring 36 is connected by" radial arms with theintermediate convey'er ring 32- and is held against vertical movementbetween the upper and lower col- 1&131393413. f a

3i represei'its the driving shaft of-tlie Inachiuc which is preferablyjournaled horizontally in bearings +l3 on the upper supporting headabove the pedestal and provided with a pulley Lifer recei ii'iy; adriving belt. This driving pulley and shaft may be connected anddisconnected'by a. clutch'tlf) of any suitable construction for startingand stopping the machine. Motion is transmitted from this drivingshaftto the several conveyer rings as follows:

f ll represents an upright intermediate shaft journaledin a bearingonthe upper supporting head and connected by into"- meshing bevel gearWheels-i6 with thedriving shaftcagear pinion e7 arranged in the lowerend of the upright shaft and meshing with an internal gear 4-8ontheupper 'dr'iving-ring 37, an upper intermediate gear pinion tSl pivotedon the uppercollar '39 and meshing on its outer and inner sides withaninternal gear 49 on the intermediate driving ring and an external gear50 on the upper driving ring, and a lower intermediate gear pinion '51pivoted on the collar 41 and meshing on its outer and inner sides withan external gear on the intermediate driving ring and an internaldriving ring 53 on the lower driving ring. By means of this driving;mechanism for the conveyer rings each ring-turns constantly in the samedirection but opposite to an adjacent ring; so that the severalrings-alternate in the direction of their rotation and the samerotatesuccessively in opposite directions.

In the operation 'of the machine vthe scans filled with goods aredelivered upon the outer conveyor rin rrthen successively transferredfrom the same to the intermediate and inner conveyer rings and. backagain from the inner ring-to the outer ring and discharged from thelatter during which time the cans are alternately conveyed throughcurved paths in opposite directions on one side of the axis of themachine and then in like manner on the other side of this axis, so thatthe cans :traverse a coinparatively long course and are thoroughlyheated by steam before being discl'ia rs ed from the machine preparatoryto being capped and sealed. The means for feeding the cans to the rotaryconveyer rings. and discharging the same therefrom are arranged onopposite sides of the machine and are preferably so constructed that thefeeding-and discharging operations may be effected on either side of themachine and thus permitof reversing the same without any change instructure and adapted the machine readily to different. conditions whichmay be met in. places where the' same may be installed. F or thispurpose two rotary tables 5st, are provided which for the present willbe referred to as the feed table and the delivery table, respectively.These tables are-arranged on a level with the conveyer rings andadjacent to diamettables is secured tothe upper end of a. hub

or sleeve 58 which is journaled on an upright stationary arbor 59carried by a bracket (31 on the adjacent part of the wall of thetreating chamber. Motion is transmitted from the lower driving ring 35to each of these tables by means which coniprise a lower uprightintermediate shaft 62 iournaled in a bearingon the lower head 23, a gearpinion 63 arranged on the upper end of the shaft (32 and meshing with anexter nal gear 64 on the lower driving ring, and a belt '65 n'eferal'ilyof the chain type passing with its inner and outer turns around beltpulleys or w heels (SO.

As the cans 100 placed on the feeding tablerotate there;- with. the same are successively pushed from the edgeportion thereof and into the inlet passage 56 of the treating" chamberby curved rake or guide 69 which is secured to the upper end of therespective arbor and upon passing through said inlet, the

vcans are directed upon the adjacent part the outer ring through theoutlet of thetreating chamber by a deflector or guide 701 extendingobliquely inwardly and rearwardly from the front edge of said outletpassage and across the adjacent part of the outer con eycr ring. As the.cmisissue from the outlet passage of the treating chamber they aredelivered upon the dalivery table and are directed upon the marginalpart thereof by means of a curved rake or guide .72 which is secured tothe upper end of the respective arbor The means whereby the cans areheated and moved from one conveyer ring to-another are constructed asfollows: 4

The pipes '73 and Ti serve the double tunctioirot main guides forguiding the cans part of thetinie in the machine when the largest sizeof cans is being heated, and also delivering steam into the treatingchamber and against'the sides of the cans. For this purpose the pipesare proyided on' theirhorizontally opposite sides with small openingsor'perforations.

Upon arr ving at tli'isinner gap.

the cans are intercepted by'a. curved guide surface 83 which shifts thecans from the intermediate conveyer ring tl'irough the inner gapto theinner conreye'r, so that the" :cans are again propelled reversely orinthe 8211116rdllTGGillQll' lll wlllcli they ywere .first moved b theouterconve er: rin The y c cans continue this, movement with the dinner.conyey'er ringiuntil: the satire-have nearly. completed a circleandhare againreached the gap. of theginner spray ring when they areintercepted by a curved guide surface 4' and; directed fronr the innerconveyer ring to theoppositely moving intermediate con: \"e'yerring."While traveling with the" inner .conveyer ring the largestcansare guidedon their oiitei'sidesbyengagement with the iii- 3 T ner side of theinner: spray pipe whiletheir f inner .sides engage with ,an inner.circula-r guide flange S5 whichisjformed on the-upper supporting head29.

lt' de; red, the operation of the machine may be reversed by turning theparts in a directionopposite from that ust described, in which case thecans are fed into the treating chamber through the opening 57 from theadjacent table and discharged through the openingeti upon the adjacenttable, this being accomplished without any change in construction of themachine, thereby enabling the same to be readily installed in placeswhich vary as to conditions of installation. When cans are to be heatedor exhausted which are of smaller diameter than the largest cans capableof being handled in the machine, the channels or runways formed betweenthe steam pipes and inner guide dange and outer wall and above theseveral. conveyor rings, are reduced in width to suit the diameter ofthe smaller cans which are to be operated upon. For this purpose meansare provided for reducing the width of the runways to suit the sizes ofthe cans to be treated, and in the preterred form of the reducing meansthe same comprise a plurality of sets of detachable and interchangeablereducing guides which are constructed as follows:

03 represent the two sections of a ci'irved auxiliary or reducing guidewhich are removably and interchangeably mounted on the outer steam pipebetween the inlet 56 and the gap between the ends of the outer steampipe. This reducing guide ovei l'uings or extends laterally andhorizontally "from opposite sides of the respective part of the outersteam pipe so as to narrow or reduce the width of the respective part ofthe can channel or runway between the outer steam pipe, the outer wallthe curved guide surface and the adjacent part of the inner steam pipe.guide consisting of two sections 94, 95 is removably and interchangeablymounted on the inner steam pipe adjacent to one side of the gap betweenits ends which sect-ions overhang this pipe laterally and horizontallyon opposite sides thereof, so as to reduce the width of the passageway01' runway between the respective part of the inner steam pipe andadjacent parts of the outer steam pipe, the inner guide flange and thecurved guide surface 83.

'( orresponding curved guide sections 96, 97

are removably and interchangeably mounted on the other end of the innersteam pipe so as to overhang laterally and horizontally therefrom onopposite sides thereof and forming a channel or runway of reduced widthbetween these guide sections and the adjacent parts of theinnerand outersteam guiding surface 86.

A similar curved pipesand the guiding surface St. Between that part ofthein'ner steam pipe not cov ered by the reducing guide sections 9:l:,95 and 90, 07 and the opposing part of the inner guide aange 85, therunway is .re-

duced in width for cans of smaller diameter than the maximum by means ofa reducing guide section 08 which is removably and iiiterchangeablysecured to the inner guide flange 85. On the opposite end of the outersteam pipe two sections 99 and 991 of a re ducing guide are removablyand interchangeably mounted so as to horizontally overhang or laterallyproject from opposite sides of the respective part of this steam pipeand serve to reduce the width of the can runway between the outer steampipe and the adjacent part of the inner steam pipe and the outerchaml'ier wall, and the Each of these removable guidesectionsispreferably, though not necessarily. made of cast metal. The

1 sections )8 are L-shaped in cross section'and secured to the flange byscrews 102 or the like. The sections 92, 93, 91', 95, 96, 9'7, 99, 991are H-shaped 111 cross section and have their webs provided withopenings or sockets 101 which receive upwardly projecting retaining pins121 arranged on the upper sides of the steam pipes. the web of eachguide section being provided with retaining lugs 103 which engage withopposite sides of each pin 121 and the adjacent part of the respectivesteam pipe to hold this giiiide section inplace, shown 'in Figs. 3, Tand 13. Inaddition to this, the guide sections are provided at theirouter ends with notches 10st, 105 which receive the inner edges of thedeflectors 70, 701, the outer ends of the guide sections 93, 99 areprovided with notches 106, 107, which receive the adjacent suspensionrods 81, 81, the outer ends of the guide sections 9T, 97 are providedwith notches 108, 109 which receive the adjacent suspension rods 81, S1and the outer ends of the guide sections 95, 96 are provided withnotches 110, 111, which receive the vertical parts of the branches T7,77 of the pipes leading steam to the inner steam spray pipe.

In practice, aplurality of sets of removable interchangeable reducingguides are provided each set being of a certain size so as to enable themachine to be organized for exhausting cans of a particular size.

It is thus possible by'this means to readily .and quickly interchangeone set of reducing guides for another in order to adapt the machine tothe particular size of cans to be treated and by omitting these reducersto fit the machine for treating cans of the largest size capable ofbeing handled by the machine.
